Skylife, Space Habitats in Story and Science – ed Benford, Gregory; Zebrowski, George

Skylife is anthology which is an excellent introduction to the genre of sci fi, especially the hard mechanics of how human might colonize space. It includes influential classics by Clarke, Asimov, and Bradbury.

You might consider it more of a reference volume than something to read for recreation. Still, if you like the nuts-and-bolts, this will catch your interest.
